Quantitative loading control system

System composition principle: distributedQuantitative loading control systemThe automated quantitative oil delivery system consists of a loading control instrument, flow meter, thermometer, liquid level switch, grounding switch, control valve, explosion-proof LED screen, upper computer, etc. The system can run independently and be operated and monitored locally by operators; It can also be connected to the computer in the control room through communication cables to achieve job control. Summarize the on-site loading situation to the control room for centralized monitoring, management, display, and printing of various loading reports by computers Main functions: 1. Automatic oil delivery and centralized management function: It can achieve automation of the oil delivery process, ensuring a maximum loading accuracy of ± 0.2% or more, and improving production efficiency
2. Safety alarm protection function: It can realize various fault alarms, as well as electrostatic overflow protection and emergency stop protection
3. Loading process monitoring function: online monitoring of the oil delivery status of each crane position
4. Ticket exchange and oil delivery: Customized printing of loading tickets and storage of these tickets, with password recognition function
5. Offline loading function: The upper computer cannot operate the room and can easily switch to on-site loading
6. Management function: Accept production data and production plans from various management networks of superiors to arrange production, and generate various reports
7. Communication networking function: Provides standard DDE and OPC interfaces, which can communicate with control and management systems such as DCS and ERP Key Features: 1. Adopt CFZ quantitative loading control instrument with domestic price and imported performance
2. Unique Ethernet and RS485 networking options
3. The communication between the upper computer and the loading instrument adopts two standard methods: TCP/IP and MODBUS RTU
4. The upper computer software can use powered configuration software for easy maintenance
5. Flexible configuration method makes the selection of on-site instruments more convenient and flexible
6. Both the upper and lower computers are in a completely Chinese language environment
7. Easy to expand and integrate with modern network technology
